Hi,
We are observing the "Unable to read execution data file" error consistently
when we run our builds on TeamCity agents that have the Linux operating system.
We believe the generated jacoco exec file is getting corrupted.
Can you please help us in resolving this error?
Jacoco version is 0.7.7.201606060606
Java version is 1.8.0_131
Ant version is 1.9.5
Following is the stacktrace of the error.
